To ascend today’s ultrathin gear-protected crack and face lines, micronuts are an essential tool. A full set of Black Diamond Micro Stoppers weigh less than a single quickdraw and opens up all sorts of protection possibilities. Micro Stoppers are made by shooting powdered iron into a die, and then melting copper into the iron. The copper fills into the iron’s grain structure, making the nuts stronger. The copper, being softer than the iron, adds ductability to the finished product. Utilizes Black Diamond’s patent-pending transverse taper shaping process.
